Subtractive encryptors: alternatives to the DES

Medical data sharing is essential for the advancement of medical research, but the existence of malicious encryptors and malicious users poses a major challenge to the seamless sharing of information among healthcare providers. We proposed a ...

This paper presents a method for detection of steganographic methods that embed in the spatial domain by adding a low-amplitude independent stego signal, an example of which is least significant bit (LSB) matching. First, arguments are provided for ...

This paper presents a novel method for detection of steganographic methods that embed in the spatial domain by adding a low-amplitude independent stego signal, an example of which is LSB matching. First, arguments are provided for modeling differences ...
